<div>Domain controller AD11 will be retired from service. Work begins on Thursday, April 24, 2026, at 8am. After a week of monitoring, it will be removed on Friday, May 1, 2026. No noticeable impact to authentication is expected. Any service or application that has AD11.cornell.edu hard coded in its config should be updated as soon as possible. Volume of traffic to this domain controller will be easily absorbed by the remaining two domain controllers for AWS specific logins.</div>
